OG exemplary drawing
 
1. An apparatus with an emulsion contained therein for removing solvent, the apparatus comprising:
a container;
the emulsion contained in the container, the emulsion comprising a first raw material of a continuous phase and a second raw material of a dispersed phase;
an impeller configured to rotate in the container to stir the emulsion; and
a foam breaker spaced apart from the impeller on an upper portion of the impeller, the foam breaker positioned below a surface of the emulsion to be submerged in the emulsion, the foam breaker configured for rotating to reduce foam generated during stirring of the emulsion,
wherein Hfb/Hliquid satisfies 0.2 to 0.5,
where Hfb is a depth from the surface of the emulsion to a center of the foam breaker, and
Hliquid is a depth from the surface of the emulsion to a bottom surface of the container.
